"We kind of like what we're seeing," Collins said of Familia's performance out of the bullpen.
Familia was impressive late in Saturday's loss, retiring the middle of the Brewers' lineup in order, including a strikeout of Aramis Ramirez. His eighth inning was the only 1-2-3 frame on the night for the Mets.
In four appearances out of the bullpen, Familia has given up two runs on five hits with five strikeouts and zero walks over five innings of work. Familia features a power swing-and-miss sinker, and he has shown the ability to throw a pretty good slider as well.
As impressive as he has been, though, the Mets remain cautious of using him on consecutive nights.
"We're pretty careful, because he's never done it," Collins said. "The one thing we don't want to do is get this guy hurt. But, boy, we're sure impressed with what we're seeing right now."
